Both planets here move quickly — Jupiter and Mars change position between people born weeks apart. That makes this aspect genuinely specific to the two charts rather than to a generation, which is true of only 59.9% of the combinations people look up.

What these two planets are doing

Jupiter

Where someone expands and what they consider worth more of.

Mars

Drive, appetite and how conflict gets handled.

At 180° the question this pairing raises is whether growth points the same direction, set against whether wanting things together produces heat or friction. A opposition puts those two demands at odds rather than in agreement, which is why this aspect is read as work rather than ease.

Jupiter moves 6.3 times slower than mars, so the faster one sets how long the exact angle holds.

If the birth time is wrong

This aspect survives 15.6 days of error

0.02° per hour — how far Mars moves, the faster of the two and therefore the one that decides.
the orb allowed for opposition. Beyond it the aspect is no longer counted at all.
Robust Even a badly remembered birth time leaves this one standing.
